Okay, so how do we proceed here? Currently Jetson TK1 is broken because
bypass mode requires the parent to be available at probe time due to new
code that's now doing a regulator_get_voltage() during the initial call
to set_machine_constraints().

Perhaps to unbreak boards the original commit that caused this failure
fa93fd4ecc9c ("regulator: core: Ensure we are at least in bounds for our
constraints") should be reverted for now?
